Not normally, but It is an issue on this system.

How much does it slow down your backup? No offense, it just does not seem like a very critical issue to me.
No offense taken. Thank you for being candid. Critical is relative to condition. In this case, catalog performance is critical.

Perhaps in most environments. I'm manually sync'ing a standby via the catalog and prompt knowledge of backup piece names is critical.


This is perhaps part of the slow resync problem...

See Metalink note 378234.1 Rman Catalog Resync Operation is Very slow at 10G
This is more of an issue when you take frequent backups.
